Question

34. (i) Define common ion effect with suitable example
(ii)The dissociation constant of acetic acid is 3.8x106. Calculate degree of dissociation of
0.01M solution.
(iii) State law of mass action
(2+2+1)​

Answer 1

Explanation:

The reduction of the degree of dissociation of a salt by the addition of a common-ion is called the common ion effect. E.g.: In a saturated solution of silver chloride, we have the equilibrium: AgCl(aq)⇌Ag++Cl−
